If part 1 mostly bored me then that was the complete opposite. I'm not sure about the conclusion (it was getting very RTD) and indeed quite why
humans should become hardrives beyond some chaos. Not helped by the lack of getting to grips with the bloom light aliens. Also the laser shoes were strawberry floating dreadful.
However free of the craptastic Bond parody it was suddenly, exciting. No explanation as to why the lights flickering was such an important thing in ep 1. Almost certainly Chibbers best episode as show runner.
Sacha Dhawan was really good I thought and it brought out the best in Whittaker. Not since The Witchfinders have I really felt 13 had the weight of the Doctor. I'm unsure about the series arc but lets see how it goes. Felt like it was retreading old ground. Effective though.
The fam sadly continue to be rather non-descript. At least occasionally amusing.
